STANDBYMODE
2h
Configuration of the local initiator state management mode. By definition, initiator may generate
read/write transaction as long as it is out of STANDBY state.
0x0 = Force-standby mode: local initiator is unconditionally placed in standby state. Backup mode,
for debug only.
0x1 = No-standby mode: local initiator is unconditionally placed out of standby state. Backup mode,
for debug only.
0x2 = Smart-standby mode: local initiator standby status depends on local conditions, i.e., the
module's functional requirement from the initiator. IP module should not generate (initiator-related)
wakeup events.
0x3 = Reserved.
3-2
IDLEMODE
2h
Configuration of the local target state management mode. By definition, target can handle
read/write transaction as long as it is out of IDLE state.
0x0 = Force-idle mode: local target's idle state follows (acknowledges) the system's idle requests
unconditionally, i.e. regardless of the IP module's internal requirements. Backup mode, for debug
only.
0x1 = No-idle mode: local target never enters idle state. Backup mode, for debug only.
0x2 = Smart-idle mode: local target's idle state eventually follows (acknowledges) the system's idle
requests, depending on the IP module's internal requirements. IP module shall not generate (IRQ or
DMA-request-related) wakeup events.
0x3 = Reserved.
